The following table shows the maximum allowed conductor trace width with the minimum conductor trace spacing, depending on the respective copper thickness.
| Copper Thickness | min. conductor trace width / space | min. annular ring |
| 18µm | 100µm | 100µm |
| 35µm | 100µm | 100µm |
| 70µm | 175µm | 175µm |
| 105µm | 250µm | 250µm |
| 140µm | 300µm | 300µm |
| 210µm | 500µm | 500µm |
| Final Copper* | min. conductor trace width / space | min. annular ring |
